1. Introduction

This document describes the functionality and electrical specifications of the

transceiver IC PN512.

The PN512 is a highly integrated transceiver IC for contactless communication at

13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation

concept completely integrated for different kinds of contactless communication methods

and protocols at 13.56 MHz.

1.1 Different available versions

The PN512 is available in three versions:

• PN5120A0HN1/C2 (HVQFN32), PN5120A0HN/C2 (HVQFN40) and PN5120A0ET/C2

(TFBGA64), hereafter named as version 2.0

• PN512AA0HN1/C2 (HVQFN32) and PN512AA0HN1/C2BI (HVQFN32 with Burn In),

hereafter named as industrial version, fulfilling the automotive qualification stated in

AEC-Q100 grade 3 from the Automotive Electronics Council, defining the critical

stress test qualification for automotive integrated circuits (ICs).

The customer recognizes that:

– since the product was not originally designed for automotive use, it will not be

possible to achieve the levels of quality and failure analysis that are normally

associated with products explicitly designed for automotive use.

– the product qualification conforms to AEC-Q100.

– all product production locations are certified according to TS16949.

• PN5120A0HN1/C1(HVQFN32) and PN5120A0HN/C1 (HVQFN40), hereafter named

as version 1.0

The data sheet describes the functionality for the industrial version and version 2.0. The

differences of the version 1.0 to the version 2.0 are summarized in Section 21

. The

industrial version has only differences within the outlined characteristics and limitations.
